@Benjamin Sykes, my worry wouldn't so much be "vacancy" as turnover, evictions, finding reliable tenants, and increased repair.

I know I was told that top flush toilets are more reliable and less prone to leaks because it gets rid of the flipper handle and the only point that could leak was the flapper.Now I see side flush toilets are back and top flush is getting harder to find.

You want to show a predictable and reliable payment pattern - like clockwork. 

Just have to make sure that the person you work with is reliable and trustworthy and also understand that they are not just going to teach you and hand you everything out of the kindness of their heart and the partnership will have to benefit them too - keep in mind that even if you make less in the beginning, what you learn from getting in there and learning the ropes is priceless!

You have to shop around and then check back with those sources you deem reliable and consistent.Lowe’s currently has a “sale” for Valentines Day I guess, on appliances that I priced at us-applianceDOTcom.

Low fixed pricing on the management means he better be sure the tenant is reliable and minimal repairs to eat up his time...

You will also need the buyer to have their GC or several GC's walk the properties to provide reliable rehab estimates if needed.        

Most MLS listings say something like "information provided is believed to come from reliable sources but is not guaranteed" I may area it is common for old houses to be listed under size in the tax records for the reasons Account Closed mentioned.

Yes, my family is very reliable and is close to the property.

Any affordable and reliable options out there for 20+ units?
